Question: If spiritual Kelim have the form of bestowal, then how can “evil forces” cling to them?
Answer: There can be no shape without Klipot (evil forces). How can a shape exist if there is no restriction? It is impossible to draw a figure if it is not limited by boundaries. It has to extend to a specific point and no further.
But who or what is restricting us? It’s our desire for pleasure. If I go a little over the edge, it’s considered “for the sake of self-gratification,” and that’s where I stop. However, at this point I am still capable of giving, so I keep looking for the “direction” and the form of bestowal. This is how the shapes of the letters are formed.
You start with a point: “I have a desire to bestow.” What next? You can move up a little bit to the right or left and by using limitations you draw a letter (a spiritual vessel,) a Kli in which two forces of the Light connect – the Lights of Hassadim and Hochma. Only two components exist: the desire for pleasure and the intention “for the sake of bestowal.” A Kli is made of the desire for pleasure, but there is a screen above it with Reflected Light – the force of bestowal. That is how a figure emerges from a point.
